Looks to me like a very good guess. All the families you list are names from around Chestnut and Mt. Pulaski, and all the German Villages of origin seem to be very close together. Would be fun to know a bit of German and spend some time searching old Lutheran Church records in that general area. So it may be Maisenberg rather than Meisenberg where Erhard Stoll family originated. Since all 3 Meisenberg locations are in other states, the only further check would be to find a German map from 1847 to be sure one of the three had not formerly been in Wurttemburg state. Sure appreciate all your help!
